Schrader Valve on Intake?
 

The Chilton's on it's way, but in the meantime... What is the schrader valve doing on what looks like the Injector/Intake manifold? what purpose does it serve?...Oh and is my 1988 BII XL R134 compatible??

Thanks again guys...

Its where you check your fuel pressuer and bleed the pressure off to change the fuel filter and the fuel pressure regulater.

Thanks Grey Ranger, I was mistaken in assuming it was how the injectors were cleaned...Whats the Fuel PSI supposed be? Im used to the German Cars, 80-100 PSI stuff...BTW, I located what I think is the ECU, or brain, under the "B" pillar, behind the driver seat, am I correct?

Thanks

The fuel pressure should be 35-40 lb with the KOEO.The ECM that you found could be the 4x4 ECM if its a 4x4,or the abs ECM on 2x4s.the ECU is behind the kick panal on the passengres side. You would have to retro fit your ac for R-134.
